Bullying is the academic concept and research domain investigating repeated aggressive behavior characterized by an imbalance of power and intent to cause harm or distress. This field systematically examines its diverse forms (e.g., physical, verbal, relational, cyber), prevalence across various contexts (e.g., educational, occupational, online), underlying causes, psychological and social consequences for all involved parties (perpetrators, targets, observers), and the development and efficacy of intervention and prevention strategies. It is characterized by a focus on the dynamics of repetition, power differentials, and intentionality of harm. The significance of this research lies in understanding and mitigating detrimental social interactions and their impacts on individual and collective well-being, informing policy and practice aimed at creating safer environments.
